The SARAH project has been launched!

SARAH (Increased Safety and robust certification for ditching of aircrafts and helicopters) is a Horizon 2020 collaborative project aiming at establishing novel holistic, simulation-based approaches to the analysis of aircraft ditching. The project is built up from a consortium of experts from OEM industries, experienced suppliers of simulation technologies, established research institutions and representatives of the certification authorities. The ambitious project has been launched in October 2016 and will be developed across a 36-month period.

SARAH Kick off meeting

IBK-Innovation GMBH & CO. KG hosted a 2-day event on October 10th – 11th 2016 during which the official launch of the SARAH project took place. Besides the formal project kick off, the meeting provided an opportunity for all partners to meet, obtain an overview of the entire project and initiate the first interactions which will take place during the course of the project.

SARAH's private area is available!

In collaborative research initiatives, communication is crucial for keeping all partners actively involved in the project. This includes on one hand the communication of the project and its results to potential stakeholders and on the other hand, we need to consider internal communication, i.e. facilitating the remote exchange of documents, optimizing the real-time involvement and update of all consortium members with regards to running and planned activities, and in overall ensuring an effortless partner-to-partner interaction upon which an effective collaborative spirit can thrive, and develop a successful project. In addition to face-to-face meetings, phone- or video-conferences and e-mails, the main internal communication tool of the consortium is a password protected area, accessible through the project’s public website, aiming to act as an internal virtual collaborative space.

Methods to create the ditch-model and simulate water impact

The methods used to create the ditch-model and simulate water impact are the following: oThe Ditch-Code, which was developed by TUHH to simulate loads created during water impact of aircrafts, is able to perform simulation of the ditching event in time, taking into account the A/C geometry, mass-distribution and approach conditions. oThe DFTS (Ditch/ Floatation Tool Suite), which was developed by IBK as pre-/ post-processing tool around ditch-code, enables the user to create ditch-models more efficiently, providing comparisons and visualisation of model and results. It is worth mentioning that both tools are continuously improved by TUHH and IBK respectively.

Global solutions

In regards to the global solutions, a model of BWB was generated by TUBS and provided to IBK. The model was implemented into DFTS-Tool and simulated using ditch-code as-is. The related results are currently analysed and the upgrade needs for DFTS/ ditch-tool are under review and in discussion with TUHH.

The SARAH public website is alive!

The project website is crucial to the dissemination objectives of the project; the internet is an efficient and widely used media of communication and thus it is one of the most important dedicated dissemination tools. The website acts as a continuous informative repository on the concept, objectives and structure of the project, while it is also updated on the latest progress activities, meetings, news, presentations, etc.

2017-03-22 07:06:58

The project website and initial communication pack is available

The communication of the SARAH results is of paramount importance for the project in order to maximize its impact and trigger effects across the project’s entire range of target audiences. To this end, a set of communication material was developed during the first months of the project, in order to facilitate partners in their dissemination, communication and networking activities.

2017-03-27 07:06:58

Dissemination Action Plan developed!

The efficient dissemination and exploitation of the important research results produced within the project is one of the key objectives of the SARAH Consortium. The aim of this deliverable is to report on the envisaged dissemination activities of the project results.

2017-03-31 07:06:58

The conditions for guided aircraft ditching tests have been defined!

The conditions that will be used for the aircraft ditching tests to be performed at CNR-INSEAN have been defined. Four different test typologies will be considered, namely they will be conducted on: double curvature rigid specimen, single curvature aircraft‐like structure, thin flat plates and scaled fuselage with dynamic pitch.

2017-03-31 19:48:07

SARAH Poster is available

The SARAH poster was developed in harmonization to the project’s leaflet, aiming to support the partners in their dissemination activities, so that it may be displayed at scientific events, technical seminars and exhibitions. The project poster was designed by EASN-TIS, following the content and layout of the leaflet.

2017-03-31 19:48:07

SARAH leaflet is available

The project leaflets aim at facilitating partners in their dissemination and communication activities. In particular, distribution of SARAH leaflets is planned to take place during participation at high-impact scientific events, technical seminars, exhibitions, etc. In this way, the expected recipients of this material will include researchers, academics, experts and industrial representatives working on similar activities and application fields, thus being greatly familiar with the technical language, challenges and objectives of simulation-based approaches to the analysis of aircraft ditching. At the same time however, SARAH leaflets will be distributed at open events, communication and networking activities, the target audiences of which may be not so familiar with the technical content, yet interested to learn about the outcomes and impact of the project. These audiences include policy makers, investors, or even European citizens. To this end, it was important to ensure that the language and illustrations that were to be used, would be easily understood by the aforementioned target audiences.

SARAH in the April 2017 issue of the EASN Newsletter

A SARAH related article has been published in the April 2017 issue of the European Aeronautics Science Network Newsletter highlighting the significant progress of the project. "At six months from the official Kick-off, SARAH is running ahead to establish novel holistic, simulation-based approaches to the analysis of aircraft ditching for improving the safety of the air transport system. The prime concern of this very dedicated consortium for the first months was the successful launch of the project and of the respective technical activities as well as the realization of the initial interactions among the partners." During this period the conditions that will be used for the aircraft ditching tests to be performed at CNR-INSEAN have been defined. In particular, four different test typologies have been decided to be considered, namely double curvature rigid specimen, single curvature aircraft‐like structure, thin flat plates and scaled fuselage with dynamic pitch. Some aspects concerning the shapes, dimensions and main structural characteristics of the specimen have been decided. All the main aspects of the test conditions have been discussed and agreed with the involved partners within the technical limits allowed by the testing facilities. For each test typology, the instrumentation adopted and the quantities that will be measured have been also defined.

SARAH in the September 2017 issue of the EASN Newsletter

A SARAH related article has been published in the September 2017 issue of the European Aeronautics Science Network Newsletter highlighting the significant progress of the project. "As SARAH is approaching to its first year of activities several important achievements have been realized. In particular, towards enhancing high fidelity simulations, the SPH model has been developed and will be tested for impact problems concerning a flat panel to which also an horizontal velocity will be imposed. Also during this period, detailed analysis of the data from SPH simulation concerning preliminary test on water impact of a flat panel has been performed. The SPH-Flow software has been used and the results have been compared with Experimental data available as well as with analytical results from potential flow theory. The comparisons were satisfactory and represent a sound base for extension to more complex problems. In regards to the preparation of the Helicopter ditching tests, the consortium is still working on the design of the experimental campaign. "
